<h2 title="Package org.apache.commons.collections4.bidimap Description">Package org.apache.commons.collections4.bidimap Description</h2>
<div class="block">This package contains implementations of the
 <a href="../../../../../org/apache/commons/collections4/BidiMap.html" title="interface in org.apache.commons.collections4"><code>BidiMap</code></a>,
 <a href="../../../../../org/apache/commons/collections4/OrderedBidiMap.html" title="interface in org.apache.commons.collections4"><code>OrderedBidiMap</code></a> and
 <a href="../../../../../org/apache/commons/collections4/SortedBidiMap.html" title="interface in org.apache.commons.collections4"><code>SortedBidiMap</code></a> interfaces.
 A BidiMap is an extension to Map that allows keys and values to be looked up with equal ease.
 One example usage is a system communicating to a legacy datasource that must convert codes
 from the new format to the old format and vice versa.
 <p>
 The following implementations are provided in the package:
 <ul>
   <li>DualHashBidiMap - uses two HashMaps to implement BidiMap
   <li>DualLinkedHashBidiMap - uses two LinkedHashMaps to implement BidiMap
   <li>DualTreeBidiMap - uses two TreeMaps to implement SortedBidiMap
   <li>TreeBidiMap - red-black tree implementation of OrderedBidiMap
 </ul>
 <p>
 The following decorators are provided in the package:
 <ul>
   <li>Unmodifiable - ensures the map cannot be altered
 </ul></div>
